THE MOUSE PAD OF MY TOSHIBA SATELLITE C855D-S5232 DID NOT MOVE (INTERMITENTLY) AND SO I INSTALLED A NEW WINDOWS 7 OS AND SINCE THEN I AM UNABLE TO DOWNLOAD VGA AND MOUSE DRIVERS IN ORDER TO BRING THE MACHINE TO ITS FORMAL STATE.
THE MOUSE SCROLLER IS NO MORE WORKING, THE GRAPHICS ARE NOT THE BEST - IN FACT WHEN I CONNECT TO A PROJECTOR, IT DOES NOT WORK.
